ePrint ReportWe show how to QOTP-encrypt classical plaintext in a nontrivial way: if a plaintext bit is encoded on the Bloch sphere as $\pm(1,1,1)/\sqrt3$ then applying the Pauli encryption operators results in eight possible cipherstates which are equally spread out on the Bloch sphere. This encoding, especially when combined with the half-keylength option of QOTP, has advantages over 4-state and 6-state encoding in applications such as Quantum Key Recycling and Unclonable Encryption. We propose a key recycling scheme based on the 8-state encoding.
We derive bounds on the distance between pseudorandom-keyed QOTP cipherstates and the fully mixed state. We present numerics up to 9 qubits.

ePrint ReportIn this paper we show how to compute the forecast prediction such that the supplier does not learn any individual consumer usage information. This is achieved by using the Fan-Vercauteren somewhat homomorphic encryption scheme. Typical prediction algorithms are based on artificial neural networks that require the computation of an activation function which is complicated to compute homomorphically. Instead of ignoring this requirement, as was done in previous work, we investigate a different approach and show that Ivakhnenko's group method of data handling is suitable for homomorphic computation.
Our results show this approach is practical: prediction for a small apartment complex of 10 households can be computed homomorphically in less than four seconds using a parallel implementation or in 90 seconds using a sequential implementation. Expressed in terms of the mean average percentage error (MAPE), the prediction accuracy is about 21%.

Event CalendarCISPA-Stanford Center (Saarbruecken, Germany & Stanford, USA)
Job PostingThe CISPA-Stanford Center for Cybersecurity is inviting applications for its
Postdoctoral & Faculty Positions (m/f) in Cybersecurity within a unique Elite Research Career Program.
The CISPA-Stanford Center for Cybersecurity was established as a joint program by CISPA - the Center for IT-Security, Privacy and Accountability at Saarland University - and Stanford University in 2016 and is supported by the German Federal Ministry of Education and Research (BMBF).
The Elite Research Career Program intends to offer the very best postdoctoral cybersecurity researchers a unique career path at two of the leading cybersecurity institutes in the world. The program consists of three consecutive phases:
• a preparatory 1-2-year postdoctoral phase (Phase P) at CISPA, followed by
• a 2-year appointment at Stanford University (Phase I) as a visiting assistant professor, followed by
• a 3-year position at CISPA as a junior research group leader (Phase II).
Applicants to the program must have completed an outstanding PhD and demonstrated their potential to become future leaders in their field of research.
Applicants should submit their CV, copies of their school and university reports, a list of publications highlighting their five most relevant ones, names of 3-5 references, a brief description of their previous research, and a research proposal outlining their research vision. Please send them as a single PDF file to: application (at) cispa-stanford.org.
Application deadline: January 30, 2017.
The CISPA-Stanford Center for Cybersecurity is an equal opportunity employer and women are encouraged to apply. Applications of severely disabled candidates with equivalent qualifications will be given priority. We intend to arrange future rounds of application periodically.
Closing date for applications: 30 January 2017

Centre for Secure Information Technologies (CSIT), Queen’s University Belfast, UK
Job PostingThe post holder will be a member of the Centre for Secure Information Technologies (CSIT). CSIT is a UK Innovation and Knowledge Centre (IKC) established in 2009 with initial 5 year funding of £30M from EPSRC/Innovate UK, industry, Invest NI and QUB. CSIT has a proven track record of success and in 2015 was awarded a further 5 years of funding from EPSRC/InnovateUK and £9M from Queen’s to build on its achievements to date as part of a package potentially worth over £38M. CSIT focuses on the electronic security of Smart Cities and the Internet of Things. In 2012 it was recognised by GCHQ and EPSRC as an Academic Centre of Excellence in Cyber Security Research and in 2015 CSIT was awarded a Queen’s Anniversary Prize for Higher and Further Education. This is a biennial award scheme within the UK’s national honours system and is UK’s most prestigious form of national recognition open to a UK academic or vocational institution. Over 20 industrial partners, large global companies as well as SMEs, have committed to supporting the centre through the provision of funding and market intelligence. CSIT has also established strong relationships with similar international centres in cyber security.

Job PostingThe goal of this project is to design methods for preventing attacks by malicious hardware manufacturers. Such attacks are possible because manufacturing of integrated circuits is frequently outsourced to external companies. Due to the complexity of these devices it is practically impossible to inspect them in order to check that they were manufactured correctly. Hence, a malicious manufacturer can alter the device\'s design, by introducing the so-called \"hardware Trojan horses\". Such devices can later cause significant damage to their users by malfunctioning, or leaking users\' secrets to the adversary. This is very worrying, especially given a tremendous dependence of modern society on the electronic devices. Another threat associated with the third-party manufacturing is the intellectual property theft and piracy, as the manufacturer gets full access to the device\'s specification. In this project we address these problems by applying state-of-the-art cryptographic techniques.
Profile:
All candidates with a PhD degree and a publication record in cryptography or data security are encouraged to apply and will be carefully considered.
We offer excellent networking and training opportunities, including participation in international workshops and conferences.
The salary will depend on qualifications and will be in the range of approximately PLN 7000 - 8,500 (net/month).
Successful candidates can start from January 2017. Funding is available for 3 years.
There is no official deadline for this call. We will start looking at the applications from Dec 15, 2016.
